1. What happens during atrial systole?

Explanation

During atrial systole, the muscular wall of the atria contracts, causing the blood to be pushed from the atria into the ventricles. This contraction results in the emptying of the atria and the opening of the atrioventricular valves.

2. What happens during diastole?

Explanation

During diastole, the heart muscle is relaxed, allowing the atria and ventricles to fill with blood. The contraction of the muscular wall of the atria pushes the blood from the atria into the ventricles, emptying the atria. This action also opens the atrioventricular valves fully. Subsequently, the muscular wall of the ventricles contracts, causing the atrioventricular valves to close.

Submit
3. What happens during ventricular systole?

Explanation

During ventricular systole, the muscular wall of the ventricles contracts, causing the atrioventricular valves to be forced shut. This contraction helps to pump blood out of the ventricles and into the arteries. By closing the atrioventricular valves, it prevents the backflow of blood into the atria and ensures that the blood is directed towards the arteries.

Submit
4.  What does 3 show?

Explanation

The correct answer is semilunar valve closing. This means that the 3 shows the closing of the semilunar valve. The semilunar valves are located between the ventricles and the major arteries leaving the heart. When the ventricles contract and blood is pumped out, the semilunar valves close to prevent backflow of blood into the ventricles. This closure of the semilunar valves ensures that blood flows in one direction, from the heart to the rest of the body.

Submit
5.  What does 2 show?

Explanation

The answer "semilunar valve opening" is correct because the question is asking what action the number 2 represents. In the context of the given options, the semilunar valve is the only valve mentioned, and the opening of the semilunar valve allows blood to flow from the ventricles to the arteries. Therefore, the number 2 represents the semilunar valve opening.

Submit
6.  What does 4 show?

Explanation

The correct answer is atrioventricular valve opening because the atrioventricular valves are responsible for allowing blood to flow from the atria to the ventricles. When the atrioventricular valve is open, it allows blood to pass from the atrium into the ventricle. The other options, semilunar valve opening, semilunar valve closing, and atrioventricular valve closing, do not accurately describe what is shown in the question.

Submit
7. What does this ECG show?

Explanation

The ECG shows tachycardia, which is a condition characterized by a rapid heart rate. This can be seen on the ECG as a consistently elevated heart rate above the normal range. Tachycardia can be caused by various factors, such as stress, exercise, certain medications, or underlying medical conditions. It is important to identify and treat the underlying cause of tachycardia to prevent any potential complications.

Submit
8. What does this ECG show?

Explanation

The ECG shows bradycardia, which is a condition characterized by a slow heart rate. This can be seen on the ECG as a prolonged PR interval and a slower than normal heart rate. Bradycardia can be caused by various factors such as certain medications, heart diseases, or abnormalities in the electrical conduction system of the heart. It can lead to symptoms such as dizziness, fatigue, and fainting. Treatment for bradycardia depends on the underlying cause and severity of symptoms.

Submit
10. What does this ECG show?

Explanation

The ECG shows signs of a myocardial infarction, also known as a heart attack. This can be determined by analyzing the pattern and shape of the ECG waves, which indicate damage to the heart muscle.

Submit
11.  What does 1 show?

Explanation

The correct answer is atrioventricular valve closing. This is because when the atrioventricular valve closes, it prevents the backflow of blood from the ventricles back into the atria. This closure occurs during the ventricular systole phase of the cardiac cycle, ensuring that blood is pumped out of the heart and into the arteries.

Submit
12.  What does this ECG show?

Explanation

This ECG shows atrial fibrillation. Atrial fibrillation is a cardiac arrhythmia characterized by irregular and rapid electrical activity in the atria of the heart. This can lead to ineffective pumping of blood, causing symptoms such as palpitations, shortness of breath, and fatigue. The ECG tracing of atrial fibrillation typically shows irregularly irregular R-R intervals, absence of P waves, and fibrillatory waves.

Submit
13. What does this ECG show?

Explanation

This ECG shows a normal and healthy heart rhythm. There are no abnormalities or irregularities observed in the ECG, indicating that the person's heart is functioning properly without any signs of myocardial infarction, bradycardia, ventricular fibrillation, tachycardia, atrial flutter, or atrial fibrillation.

Submit
14. The wall of the heart is made up of a very special kind of muscle called ______ muscle. It is special because it does not need any stimulation from a nerve to make it contract. We say that it is ________.

Explanation

The wall of the heart is made up of a very special kind of muscle called cardiac muscle. It is special because it does not need any stimulation from a nerve to make it contract. We say that it is myogenic.

Submit
15. Label numbers 1 - 15. Seperate with a coma and then a space. (For example: aorta, pulmonary artery, semilunar valve, ect)
